Day 4

Observations



-low tide
-a lot of small schools of fish
-birds seem to be scavegering for food
-all of the schools of fish seem to be small fish

Day 5

Observations


-high tide
-there doesn't seem to be any birds scavegering around
-there are more fish swimming around
-not all the schools of fish are such small fish
-many of the smaller fish seem to have moved to areas where it is really shallow, where the bigger fish can't get to


A lot of the observations that I took were pretty much the same as all the times I have taken observations before. So there really Isn't a difference or at least not much of a difference in the area i have been studying throughout the study.


Experiment

For this experiment I was trying to see if during low tide there were smaller fish and if during higher tide there seem to be bigger fish then when it is lower tide.

So basically for this experiment I visited my site a couple of times and tried to visit it when the tides were different. Luckily both times I went the tides were different. So I looked around to try and see if the fish were bigger or smaller during high or low tide. There was a difference when it was high and low tide. During low tide there only seemed to be very small fish. When it was high tide there were both the really small fish and also some bigger looking fish appeared to be swimming around too. I also took the observations from the other three times I went and used it to come to my conclusion about if during high tide there are bigger fish and if during low tide there are smaller fish. I agree that during low tide there are smaller fish and during high tide there are larger fish. I think that the larger fish don't come during low tide because there isn't enough room for them to move around without scraping themselves or bumping into things. Also I think that the bigger fish don't want to get stuck in tide pools and have to wait a couple of hours for high tide.


Assigned Journal Writing

Well the carbon cycle is mostly due to the organisms at our site. The fish take in oxygen from the water that is produced from the plants. This oxygen in the fish is then used up to breathe. The oxygen turns into carbon dioxide, which is put back into the water and the plants take it in and turn it back into oxygen. Also when plants decay or when fish die they sink to the bottom of the sand. The sand then holds a lot of the carbon. Decomposers probably go and eat up the fish or dead plants and change it into somethings else. Also the ocean current will distribute dissolved carbon to different areas of the community. Plants are also producing carbon dioxide, but in smaller amounts then they are changing into oxygen and glucose. Plants produce carbon dioxide through a process called cellular respiration. Carbon is being cycled through all of these organisms, current, and the ocean floor.
